TC-1在非小细胞肺癌的表达及与淋巴结转移的关系

目的:探讨TC-1蛋白在非小细胞肺癌(NSCLC)组织中的表达及其在病理分类、分级、TNM分期中的差异性,为进一步研究TC-1在NSCLC中的作用及其机制提供依据。方法:采用免疫组化EnVinsion法检测TC-1蛋白在95例非小细胞肺癌中的表达,统计学分析其在病理分类、分级及临床TNM分期及淋巴结转移与否的差异性。结果:免疫组化结果显示TC-1阳性表达主要位于胞浆中和部分胞核。肺鳞癌和腺癌总阳性率分别为63.46%、72.09%,差异性不显著(P=0.154)。鳞癌高、中、低分级阳性率分别为20.00%、65.51%、72.22%,经Kruskal-Wallis H检验无明显差异性(P=0.075)。腺癌的高、中、低分级的阳性率分别是33.33%、65.21%、88.23%,差异性非常显著(P=0.005)。NSCLC(鳞癌、腺癌)的TNM分期Ⅰa、Ⅰb、Ⅱa、Ⅱb、Ⅲa、Ⅲb的表达强度经检验差异性显著(P=0.029)。有淋巴结转移者原发灶阳性率为90.57%(48/53)、无淋巴结转移者原发灶阳性率为38.09%(16/42),经Mann-Whitney U秩和检验差异性非常显著(P=0.000)。53例伴淋巴结转移的NSCLC原发灶与淋巴结转移灶阳性表达相关性用Spearman检验,有相关性(r=0.39,P=0.000)。结论:TC-1在非小细胞肺癌(NSCLC)组织中高表达,TC-1表达与病理分型、鳞癌分级无关,与腺癌分级、NSCLC TNM分期、淋巴结转移与否相关。提示TC-1在肺癌组织中表达高低与淋巴结转移密切相关。

Expression of TC-1 in NSCLC, lymph node metastasis and its clinical significance

Objective:To investigate the expression of TC-1 protein and analyze the relationship between TC-1expression and pathological types,grades and TNM stages in the non-small cell lung cancer(NSCLC).Methods: The expression rate of TC-1 protein in NSCLC was detected with immunohistochemical method-EnVinsion method;the differences of the protein expression among pathological types,grades and TNM stages and lymph node metastasis were analyzed.Results: The TC-1 positive expression was mainly located in the cytoplasm...
